7. Images

facsimile is the element devoted to the reproductions of the edited seals and indicated where to locate the images.

A <surfaceGrp> element groups together all the photos chosen to illustrate the edition, organised according to a <surface @n="r"> element for the obverse and a surface @n="v" element for the reverse: each surface element can contain a potentially unlimited number of <graphic> elements for different photos of the same face. In <graphic> a @url attribute gives the path to the folder, website, etc. where the image is located, while a required @type attribute specifies the nature of the reproduction presented, according the a list of suggested values; with a @scale attribute the scale of the image should be mentioned (ex. 0.5, 1, 1.5, etc.).

Nested inside <graphic>, the <desc> element contains a caption for the image (it is repeatable for different languages). It should consist of:

• the mention of the type of reproduction (digital, drawing, etc., possibly with bibliographic reference);
• when the image has been taken (at least the year);
• if no image is available, this should be mentioned here.
